Application September 8, 1934, Serial No. 743,201

' 1 Claim. (01. 139-420) My invention relates to certain new and useful features as well as certain novel details of conimprovements in textile fabrics and more particstruction, all of which will appear more fully ularly to a tape adapted especially for use as from the following description and accompanylingerie tapes or shoulder straps or the like. ing drawing.

5 It has been the practice in making shoulder For the purpose of illustrating my invention, 5

straps for lingerie or the like, to form them of I have shown in the accompanying drawing, one ordinary thin silk fabrics or silk cloths, which, form thereof which is at present preferred by according to the usual practice, are cut into narme, since the same has been found in practice to row strips of a width slightly greater than twice e Satisfactory a d reliable results, although 0 the desired width of the shoulder straps or tapes it is to be understood that the various instruor he like, and these strips of the silk fabric are mentalities of which my invention consists can then folded longitudinally and their juxtaposed be variously arranged and organized and that my cut edges in-turned and then seamed by a suitinvention is not limited to the precise arrangeable line or l nes of sewn stitches, thereby proment and organization of the instrur'nentalities as ducing a relatively narrow band or tape of a herein S ow d desc bed.

two-ply formation with the longitudinal edge or R rrin to e raw in which lik r f redges bound by a row or rows of sewnstitches. e Characters indicate like D s The object of my present invention is to form Figure 1 represents a p D1811 V w Of a Small lingerie tapes for shoulder straps and the like, piece f the p Structure embodying y v nto which will have the appearance of the cut-andn Shown '1 a much enlarged ca e sewn lingerie tapes hereinabove described but Figure 2 represents a Section generally On line which will be integrally woven in a two-ply for- 2 o Figure mation so as to give the appearance of a cut-and- Figure 3 represents a Sec generally o l sewn tape, and which will be cheaper and yet f Figure :5 superior thereto. Figure 4 represents a section generally on line A further object of my invention is to produce -4 of Figu e 1. integrally woven tapes of this character which It will be understood that in the drawing, th will be inexpensive to produce and which will p ion e n c ura and that p r i upossess greater durability and certain other delarly the sectional views are to be recognized more sirable characteristics and qualities not present as c e c representatiens, Since in the actual in the cut-and-sewn tape construction heretofore structure the several plies lie closer to each other, used. than is shown in the drawing;-the latter being With the above and other objects in view, more for purposes of illustration of the weave which will appear more fully from the following and structure rather than for the exact dimendescription and accompanying drawing, my insional relationship or spacing of the parts. vention consists of a tubular woven textile tape e fabric Structure Of y Present ven structure formed of relatively loose or untwisted i c es WO t f relatively dull a relatively and relatively dull warps having no twist or but untwisted r r iv y wis -fre y n W p a slight amount of twist, and weft threads having y ns 5 a d 6 p v y, a Set being Shed a substantial twist and extending alternately epa ely of and alternately t0 the other but 40 through the two different plies of said warps of in conjunction with the same relatively twisted the fabric structure;--that is, woven alternately cotton Weft thread extended a e a e y (backthrough two different sheds of said warps;--and and forth) through the two different and alter-' a relatively few bright or lustrous rayon or silk nating sheds the W different e w p warp threads grouped near each of the two longi- 5 and 6. tudinal selvages of the fabric structure, but Near each of the selvages, designated generspaced inwardly therefrom to a slight extent, and ally by the numerals 8 and 9, a relatively few shed with each two successive picks of the weft (two,'four or six) warp threads 10 are provided instead of alternately as the first hereinabove of a more lustrous rayon or silk or the like, in mentioned dull warp threads, thereby to cause place of the dull rayon warps 5 and 6 comprising the two plies to merge into a single ply throughthe rest of the warp structure of the fabric;-- out the zones of these two groups of lustrous these lustrous rayon or silk warps 10 being rayon or silk warps, thereby simulating the apgrouped together in two separate groups (as inpearance of sewn stitches in these zones. dicated particularly in Figures 1 and 2) a slight My invention further consists of other novel distance inwardly of the selvage edges but spaced iii generally equally from their respective selvage edges.

The lustrous rayon or silkwarps 10, just as the relatively duller rayon warps 5 and 6 are relatively untwisted or free of twist, or but slightly twisted, so as to spread out more or less flatly over the relatively more twisted cotton weft threads 7 as indicated more particularly in Figures 1 and 2 ;-while the weft thread 7 is relatively highly twisted so as more firmly to retain its form or its cross section, and thereby to be more completely concealed by the softer warps.

The lustrous rayon or natural silk warps 10 being relatively more lustrous than the relatively dull rayon warp threads 5 and 6, produce a contrast'in the zones the warp threads 10.

This contrast, due to a difference in luster or sheen, is augumented by the passage of the warp threads 10 through both two successive (back and forth) picks or traverses of the weft '7, which units the two plies into a single ply in the zones of the warps 10. This is done by keeping the shed of the warps 10 open for two successive picks or traverses of the weft 7, that is, for a back and front movement or a complete cycle of the shuttle, while the rayon warps 5 and rayon warps 6 are shed separately and alternately;- one set of warps (5) receiving the weft in one direction of the shuttle and the other set of warps (6) receiving the weft in the reverse direction of the shuttle. This relation of the warps 10, accentuates the contrast and binds the two plies firmly together near the selvage edges of the fabric structure, thereby also giving reinforcement to the edges.

By the fabric-structure of my present invention, a tape is produced having the two plies of generally tubular formation, but maintained in a fiat condition, and also reinforced, by two small groups of warp threads extending through both plies and presenting a simulation of sewn stitches near these selvage edges.

By reason of the twist in the weft and absence of twist in the warp and further by reason of the fact that the weft threads are of cotton, while the warp threads are principally of rayon, the latter are caused substantially to cover the weft threads so as to conceal the same and to give a soft smooth surface on both faces of the fabric structure.

While the warp threads 5 and 6 have been de scribed as a dull rayon, it is to be understood that any other relatively dull multi-filament yarn may be employed, as'for instance, cellulose acetate yarns or other regenerated cellulose yarns or cellulose derivative yarns which are either naturally dull or which have been delustered, Likewise, the lustrous or bright warps 10 may also be formed of acetate yarn or other regenerated cellulose derivative yarns or even si1k;the essential requirement being in this regard that there be contrast between the warp threads 10 and Warp threads 5 and 6 by virtue of difference in luster or sheen. The warp threads 5 and 6, as stated, each comprise many individual filamentswhich are related to each other in each strand or yarn with but very little or no twist. The warp threads 10 are likewise formed of a great many individual filaments and also preferably related to each other without twist or with very little twist.

I am aware that my invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive, reference being had to the appended claim rather than to the foregoing description to indicate the scope of the invention.

Having thus described my invention, what I hereby claim as new and desire to secure by Letters Pattrt is:

, Lingerie tape or the like comprising two separate sets of relatively dull multi-filament regenerated cellulose warp threads relatively free of twist, a relatively twisted cotton weft thread extending alternately through said two sets of dull warp threads and forming therewith two separate plies in continuation of and in generally tubular relation to each other and two groups of relatively lustrous multi-filament regenerated cellulose warp threads devoid of any substantial twist spaced inwardly a slight distance from the respective longitudinal edges of the tape and having each set thereof common to two successive picks or traverses of the weft and extending completely through both plies of ,-the structure, thereby merging the two plies of the otherwise tubular fabric structure into single plies throughout the narrow longitudinal zones of said two sets of lustrous warp threads and thereby reinforcing the marginal portions of the tape and forming contrasting lines on both faces of the tape near the edges thereof in simulation of sewn stitches.
